4 Claims.

This invention relates to improvements in fence post extension arms, andhas for one of its objects the provision of a novel structure togetherwith novel means for securing the same to a conventional angular fencepost.

Another object of the invention is to provide an improved fence postextension arm which may be made to occupy one of a number of adjustedpositions, in extending either inwardly or outlO wardly from the fenceline while supporting suitable fencing. material, such as barbed wire,together with improved clamping means for maintaining the structure inits adjusted position.

These and further objects will appear after referring to the drawing, inwhich:

Figure 1 is a plan view of the apparatus of the invention installed inuse.

Figure 2 is an elevation, shown partly in section. Figure 3 is a planview, showing the base of the extension arm of the invention in section,and taken on line III-III of Figure 2.

Figure 4 is a plan view of a modification, showing the extension arm insection.

Figure 5 is a sectional elevation taken along the lines V-V of Figure 4.

Figure 6 is a plan view of a further modication, showing the extensionarm in section.

Referring more particularly to the drawing, the numeral 2 designates anangular fence post of conventional design. An extension arm 3 is adaptedto be secured to the fence post 2 and is provided with a base portion3fL which is shown in the drawing as being polygonal in shape and havinga continuous groove 3c. 'Ihe fence post extension arm 3 is also providedwith a plurality of apertures 3b for receiving fencing, such as thebarbed Wire 4.

The numeral 5 designates a right angular clamping member, which isadapted to seat against the outside of the similarly shaped fence post2. A cooperating clamping member 6 is provided with a number ofrelatively angular surfaces 6a, conforming to those of the base portion3a of the fence post extension arm, and an integral projection 6b whichis adapted to seat in the groove 3C. The base portion 38L of the fencepost extension arm is disposed between the inside of the angle of thefence post and in contact therewith, and is received on its othersurfaces by the corresponding surfaces 6a in the clamping member 6,which is secured to the outside clamping member 5 in any suitablemanner, such as the bolts and nuts 7 and 7a, respectively.

Referring to Figure 4 of the drawing, a modied and continuous clampingmember is shown at 8, and is provided with a continuous recess 8a forthe angular fence post 2, and a plurality of surfaces 8b conforming tothose of the base portion 3a of the extension arm. A screw 10 isthreaded through the continuous clamping member 8 and seated in thecontinuous groove 3c in the base portion 3a for rigidly clamping theextension arm to the fence post.

Referring to Figure 6, a further modification is shown and comprises asingle clamping member 9 provided with clamping fingers 9a for makingcontact with the outer sides of the ends of the flanges of the fencepost, the remainder of the construction being the same as that of themodication shown in Figures 4 and 5.

While I have shown and described several specific embodiments of myinvention it will be understood that I do not wish to be limited exactlythereto, since various modifications may be made without departing fromthe scope of my invention, as defined in the following claims.

I claim:

1. In combination with an angular fence post, a vertically inclinedextension arm provided with a base portion having a plurality of Contactsurfaces, a continuous groove in said base portion, a continuousclamping member enclosing said fence post and the base of said extensionarm, and a screw associated with said clamping member and adapted toseat in said continuous groove.

2. In combination with an angular fence post, a vertically inclinedextension arm having a base portion provided with a multiplicity ofcontact surfaces, a right angular clamping member adapted to makecontact with the outside of said angular fence post, a cooperatingsecond clamping member having surfaces conforming to those at the baseportion of said extension bar, and fastening means for clamping saidbase portion between the inside of said angular fence post and said lastnamed clamping member. l

3. In combination with an angular fence post, a vertically inclinedextension arm provided with a base portion of polygonal shape, aclamping member provided with fingers for making contact with theoutside of said angular fence post and receiving surfaces for saidpolygonally shaped base portion, and means associated with said clampingmember for rigidly holding said base portion against the inside of saidangular fence post.

4. In combination with an angular fence post, a vertically inclinedextension arm provided with a base portion of polygonal shape, said baseportion having a groove and a clamping member having surfaces conformingto those of said base portion and a projection adapted to seat in saidgroove, said clamping member being adapted to rigidly secure saidextension arm to said fence post.
